Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater recycling treatment structure for metal processing. Background Technique

[0002] Metal processing wastewater refers to wastewater containing heavy metals discharged during industrial production processes such as mining, metallurgy, machinery manufacturing, and electroplating. Generally, it contains heavy metals such as cadmium, nickel, mercury, and zinc. It is the industrial wastewater that causes the most serious environmental pollution and the greatest harm to humans. The heavy metals in metal wastewater generally cannot be decomposed or destroyed. They can only transfer their existence positions and change their physical and chemical forms, making them difficult to treat. When they accumulate to a certain limit in water bodies, they will cause serious harm to the water environment and may affect human health through the food chain. Heavy metal wastewater is produced in many production processes in industries such as mining, metallurgy, machinery manufacturing, and electroplating, seriously affecting human health.

[0003] Traditional wastewater treatment equipment often removes sediment and floating impurities from wastewater through a filter screen. Since the filter screen has to bear the impact force of water flow for a long time and is prone to clogging due to filtering impurities, it is necessary to disassemble and clean the filter screen at this time. However, the disassembly of the filter screen of traditional equipment is too complicated, and the filter screen cannot be disassembled and cleaned in time, resulting in the filter screen losing its function during the process of filtering wastewater.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to Figures 1 to 3, in the embodiment of the present utility model, a wastewater recycling treatment structure for metal processing includes a base 1, a first circulation pipe 4, a second circulation pipe 5, an arc-shaped connecting pipe 6, a sewage inlet pipe 7, a sewage discharge pipe 10, a rotary filtering component, and a liquid guiding component; a fixing rod 2 is fixedly connected to the base 1, and a connecting frame 3 is fixedly connected to the fixing rod 2. The first circulation pipe 4 is fixedly connected to one side of the connecting frame 3, and the second circulation pipe 5 is fixedly connected to the other side of the connecting frame 3. The top of the first circulation pipe 4 is higher than the top of the second circulation pipe 5, and the bottoms of the first circulation pipe 4 and the second circulation pipe 5 are flush. The arc-shaped connecting pipe 6 is connected between the bottoms of the first circulation pipe 4 and the second circulation pipe 5. The sewage inlet pipe 7 is fixedly connected to the first circulation pipe 4, and the liquid outlet 8 at the top of the sewage inlet pipe 7 is arranged at the top of the first circulation pipe 4. The bottom of the sewage inlet pipe 7 passes through the arc-shaped connecting pipe 6 and is arranged outside the arc-shaped connecting pipe 6. The sewage discharge pipe 10 is fixedly connected to the bottom of the second circulation pipe 5, and a filter screen 11 is arranged at the connection between the sewage discharge pipe 10 and the arc-shaped connecting pipe 6; the rotary filtering component is arranged between the tops of the first circulation pipe 4 and the second circulation pipe 5, and is used to realize the circulating flow of the wastewater between the first circulation pipe 4 and the second circulation pipe 5, and filter the flocculants in the flowing wastewater at the same time; the liquid guiding component is connected to the sewage inlet pipe 7 and the sewage discharge pipe 10, and is used to inject wastewater into the sewage inlet pipe 7, and at the same time discharge the filtered wastewater along the sewage discharge pipe 10, and the water inflow is consistent with the water discharge. First, the present utility model injects sewage into the device along the sewage inlet pipe 7 through the liquid guiding component to fill the device with sewage, and then extracts the sewage in the device along the sewage discharge pipe 10 through the liquid guiding component. At this time, the water inflow is consistent with the water discharge, and the total amount of sewage in the device remains unchanged. At this time, when the sewage enters the first circulation pipe 4 along the sewage discharge pipe 10, the sewage directly enters the circulating filtering component from the liquid outlet 8. And because the flow rate of the sewage in the liquid inlet is higher than that of the sewage in the first circulation pipe 4, the sewage in the first circulation pipe 4 is also driven by the high-speed flowing sewage and enters the rotary filtering component, so as to circularly filter the flocculants in the wastewater through the rotary filtering component. The filtered sewage flows into the second circulation pipe 5, and the sewage in the second circulation pipe 5 is then discharged along the sewage discharge pipe 10 under the suction of the liquid guiding component. And during the discharge process, because the flow rate of the second circulation pipe 5 is larger than that of the sewage discharge pipe 10, the remaining sewage in the second circulation pipe 5 flows back into the arc-shaped connecting pipe 6. And during this process, the sewage flowing into the sewage discharge pipe 10 is filtered through the filter screen 11. The filtered sundries accumulate on the filter screen 11 and flow into the arc-shaped connecting pipe 6 under the scouring of the wastewater flowing towards the arc-shaped connecting pipe 6, and then flow back into the rotary filtering component along the first circulation pipe 4 again, so as to realize the circular filtering of the flocculants in the wastewater, thus avoiding the blockage of the filter screen 11.

[0022] In a case of this embodiment, please refer to Figures 1 to 3, the rotary filtering component includes a filtering hopper 17 fixedly connected between the tops of the first circulation pipe 4 and the second circulation pipe 5. The filtering hopper 17 is inclined. A rotating shaft 18 is rotatably connected inside the filtering hopper 17. Multiple groups of rotating filter plates 19 distributed in a circumferential manner are fixedly connected to the rotating shaft 18. A motor 21 is fixedly connected to the outer wall of the filtering hopper 17. The output shaft of the motor 21 is fixedly connected to the rotating shaft 18. A material dropping slope 22 is arranged at the connection between the filtering hopper 17 and the second circulation pipe 5. A collecting hopper 23 is arranged at the bottom of the material dropping slope 22. The collecting hopper 23 is fixedly connected to the outer wall of the second circulation pipe 5. By setting the top of the first circulation pipe 4 higher than the top of the second circulation pipe 5, the filtering hopper 17 is kept inclined, with the end close to the first circulation pipe 4 being higher and the end close to the second circulation pipe 5 being lower. At this time, the sewage flows from the first circulation pipe 4 to the second circulation pipe 5 and passes through the filtering hopper 17 during this process. At this time, the motor 21 drives the rotating shaft 18 to rotate, the rotating shaft 18 drives multiple groups of rotating filter plates 19 to rotate, and the rotating direction of the rotating filter plates 19 is opposite to the flowing direction of the wastewater in the filtering hopper 17. At this time, the rotary filtering component filters the flocculants in the sewage flowing through the filtering hopper 17 through the rotating rotating filter plates 19. The filtered flocculants accumulate on the rotating filter plates 19. When the rotating filter plate 19 with accumulated flocculants rotates to the material dropping slope 22, the rotating filter plate 19 is parallel to the material dropping slope 22, and it is selected that the end of the filter plate close to the rotating shaft 18 is higher and the other end is lower, and the side with accumulated flocculants faces upward. At this time, the flocculants on the rotating filter plate 19 slide down along the rotating filter plate 19 to the material dropping slope 22 under the action of gravity, and then slide down the material dropping slope 22 to the collecting hopper 23, thus completing the filtering of the flocculants in the wastewater.

[0023] In one case of this embodiment, please refer to Figures 1 to 3 , a sealing block 20 is fixedly connected to the end of the rotating filter plate 19 far from the rotating shaft 18. The rotary filtering component seals between the rotating filter plate 19 and the filtering hopper 17 through the sealing block 20, thereby preventing the leakage of flocculants in the sewage.

[0024] In one case of this embodiment, please refer to Figures 1 to 3, the liquid guiding assembly includes a liquid inlet pump 13 and a liquid suction pump 15. The liquid inlet pump 13 and the liquid suction pump 15 are installed on the base 1. The liquid inlet end of the liquid inlet pump 13 is connected to a sewage inlet 24, and the liquid outlet end of the liquid inlet pump 13 is connected to a third connector 14. The liquid inlet end of the liquid suction pump 15 is connected to a fourth connector 16, and the liquid outlet end of the liquid inlet pump 13 is connected to a sewage discharge port 25. The bottom of the sewage inlet pipe 7 is fixedly connected to a first connector 9, and the bottom of the sewage discharge pipe 10 is fixedly connected to a second connector 12. The first connector 9 and the third connector 14 are connected by a hose, and the second connector 12 and the fourth connector 16 are connected by a hose. Through the setting of the liquid inlet pump 13, the liquid guiding assembly sucks the sewage communicated with the sewage inlet 24 and pumps it into the sewage inlet pipe 7. At the same time, through the setting of the liquid suction pump 15, the sewage in the second circulation pipe 5 is sucked along the sewage discharge pipe 10 and pumped out through the sewage discharge port 25. Moreover, the power of the liquid inlet pump 13 and the liquid suction pump 15 is the same.

[0025] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms.
